如何添加实体引用作为表单字段drupal 8？ 我可以吗？

Question

What I'm trying to achieve is simple config for a plugin. I need entity reference field where users can add certain products to the config using autocomplete field. I tried to use Config Entity but It seems to look the same as Form Api and I can't use entity fields there. I can't wait to see you reply.

Answer 1

I was able to do this in Drupal 8 using the form API and the entity_autocomplete type.

$form['stories'] = [
    '#type' => 'entity_autocomplete',
    '#target_type' => 'node',
    '#title' => $this->t('Stories'),
    '#description' => $this->t('Select some stories.'),
    '#default_value' => $default_entities,
    '#tags' => TRUE,
    '#selection_settings' => array(
        'target_bundles' => array('page', 'article'),
    ),
    '#weight' => '0',
];

Use webform - there is an entity reference field. This won't be useable for your purpose .. but you can check the source for sake.
